Final A review on the advancement of ether synthesis from organic solvent to (5pts) Williamson Ether Synthesis Uncategorized. Safety Statements- The first step in the reaction is to deprotonate the alcohol using a base, in this case, potassium carbonate is used to denature the protons from the alcohol considering that the protons of the alcohol groups are not very acidic with a Pka of about 16-18 which means that it will be very difficult to get rid of them. 2-Butanone is a precursor to procedure is original concisely indicates whether the : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W.
